Hi, we've got nasty smells coming out of the wastes, principally shower, in our bathroom. We've used drain cleaner and flushed through but the smells remain.
The set up is WC waste into external stack; a couple of feet below, bath, washbasin and shower (in that orde) into the same stack. The stack is open to the air above not above roof height but a couple of feet above the WC waste). There is no evidence of an internal durgo valve (if they are internal).
Someone suggested a flap in the stack may have stuck or broken/perished. If so, where would this be?
Anyone have any suggestions?
Thanks.
